摘要:
A communication apparatus includes a communication unit for performing a communication, a speech communication unit for performing a speech communication, a detection unit for detecting the telephone number of the calling side before connection of a call, a registration unit for registering the telephone number of the calling side, and a switching unit for switching a communication mode between the communication unit and the speech communication unit on the basis of the telephone number of the calling side detected by the detection unit, and the telephone number registered in the registration unit.

A communication apparatus receives the identification information of a partner station, and performs a communication operation in accordance with the received identification information. A first detecting unit detects a calling signal. An identification information receiving unit detects the identification information of a calling party upon detection of the calling signal, and a second detecting unit detects whether or not the terminal of the calling party is a data communication terminal. A registration unit registers the identification information of the partner station in a memory, so that whether the partner station is a speech or data communication terminal can be discriminated later. A control unit checks if the identification information receiving unit receives the identification information of the calling party. When the identification information of the calling party is received, the control unit checks if the-received identification information is registered in the memory, and selectively executes a speech communication process and a data communication process in accordance with the checking result and the detection result of the second detecting unit.

A communication system in which when an incoming call has arrived, a communication line having the capability of a high sampling rate is automatically selected without assistance of an exchange operator by transmitting an ultra high speed modem indication signal indicating the capability of data communication at an ultra high speed modem rate among the capabilities of a called terminal, and receiving an ultra high speed modem capability signal indicating the capability of an ultra high speed modem of a calling terminal.

A facsimile communication system and a communication apparatus reduce a loss time due to the synchronization of transmission/reception and shorten a communication time. They also shorten a communication time in a full duplex communication mode and allow proper switching of the full duplex communication at the transmission/reception replacement. DIS-CFR signals, EOP-DCN signals, NSS-TSI signals and TSI-DCS signals of a facsimile communication protocol are connected by synchronization signals so that the synchronization signals are sent even after the sending of the protocol signal. Thus, the sending of the synchronization signal for one second when the next protocol signal is sent is not necessary and a time required for the protocol signal is shortened. An ANSam signal to disable a function of an echo suppressor is sent when a call is detected and a calling station thereafter sends a protocol signal and an image signal in a manner not to cause signal interruption of 50 ms or longer, and at transmission/reception replacement at the end of the image signal from the calling station, a called station sends an ANSam signal and sends a protocol signal.

In an Internet facsimile apparatus, it is an object of the invention to provide means for notifying the user of details of a message disposition notification situation (MDN) of a transmission image. When E-mail data is sent, an MDN for E-mail to be sent is requested and communication management information of the sent E-mail is updated on the basis of a reception result of reply E-mail responsive to the MDN request.

In an image communication apparatus for communicating a color image with a distant apparatus according to the ITU-T recommendations upon line connection, an original image is read by a scanner unit, and the size of the read original image is identified. If the identified size of the original image is smaller than the page size defined by the ITU-U recommendation, image data is generated by reading the original image upon adding invalid data to the original image to make it have a main scanning length equal to the main scanning length of the minimum page size defined by the ITU-T recommendation in reading the original image through the scanner unit, and the image data is compressed by a JPEG compressing unit and transmitted. In this case, the valid image area of the compressed data is set in accordance with the size of the original image. This allows the receiving side to read only the valid image area, decode the valid image area, and reproduce the image.

摘要:
Disclosed are a monochrome facsimile apparatus capable of supporting communication of color information in sYCC color space, and a color-information communication method that uses this facsimile apparatus. If a compact flash card has been inserted into the monochrome facsimile apparatus, which is capable of communicating color file information, the facsimile apparatus notifies the transmitting side, by prescribed bits of the FIF of a DIS signal, that it has a function for receiving JPEG-coded information, lacks a function for receiving full-color information in Lab color space, and has a function for receiving full-color information in sYCC color space. If the facsimile apparatus senses, by prescribed bits of the FIF of a DCS signal, that a designation to transmit full-color information in sYCC color space has been received from the transmitting side, then the facsimile apparatus is allowed to receive color information, which is then stored on the compact flash card without being printed, by information receiving means having the function for receiving JPEG-coded information and the function for receiving full-color information in sYCC color space.
